(57) [Summary] [Object] To provide a liquid crystal composition capable of improving low voltage driving of a liquid crystal element, temperature dependence of driving voltage, and speed of electro-optical response. [Structure] A liquid crystal composition containing the following first to fourth components. First component: Formula I, Second component: Formula II, Third component: Formulas III to V, Fourth component: Formula VI or VII In the formula, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 9 are C 1-8 alkyl, n, m, p, q and r are 0 or 1, and R 8 And R 10 is C 1-8 alkyl or alkoxy or C 2-8 alkoxymethyl, A 1 is 1,4-cyclohexylene, 1,4-phenylene or 1, 3-dioxane-2,5-diyl, A 2 and A 5 are 1,4-cyclohexylene, 1,4-phenylene or pyrimidine-2,5-diyl, A 3 , A 4 , A 6 and A 7 Is 1,4-cyclohexylene or 1,4- Phenylene, Z 1 , Z 3 and Z 6 are -COO- or a single bond, Z 2 and Z 4 are -CH 2 CH 2- , -CH = CH- or a single bond, and Q and Z 5 are -CH. 2 C H 2 - or a single bond, L, X and T are F or H, S is F, Cl or CF 3 is shown respectively. |
